A transceiver is a device that has both a ​​transmitter​​ and a ​​receiver​​ which are combined and share common circuitry or a single housing. If no circuitry is common between transmit and receive functions, the device is a transmitter-receiver. The term originated in the early 1920s. Technically, transceivers must combine a significant amount of the transmitter and receiver handling ​​circuitry​​. Similar devices include ​​transponders​​, transverters, and repeaters.
